θJA

θJC

QFN16 (4x4mm)..................... 46 ...... 10... °C/W

Notes:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum junction temperature TJ(MAX), the junction-to-

ambient thermal resistance θJA, and the ambient temperature

TA. The maximum allowable continuous power dissipation at

any

ambient

temperature

calculated

PD(MAX)=(TJ(MAX)-TA)/θJA.

Exceeding

the

maximum

allowable power dissipation will cause excessive die

temperature, and the regulator will go into thermal shutdown.

Internal thermal shutdown circuitry protects the device from

permanent damage.

3) The device is not guaranteed to function outside of its

operating conditions.

4) Measured on JESD51-7 4-layer board.
